Be it known that T, Gnonen a citizen of the United States, residing in the City of St. Louis and State of :t/ilissouri,

' The present invention pertains to briquet making machines, for use in converting composite fuel, made up of slack coal, tar, and saw dust, or other suitable materials properly' mixed together, into globular briquets for convenient use in stoves and furnaces.

The primary object of the invention is to provide a practical machine for this purpose constructed in an efiiclent and durable form. I 7

Another object is to provide such a machine wherein the'material will rest freely within the molds of the drums, thus preventingthe shearing'or splitting ofthebriquets. Another object is to providesuch a machine, the drums whereof are reslliently held into relation with one another b means of springs or the equivalent, so ad uSted. relatwo to bearings which press upon one of the drums that the said drum will be always held properly adjusted relative to the other drum so as to prevent shearing of the briquets.

Another ob'ect is to provide a mold drum, the molds w ereof are separable and detachable from the drum shell, so as to. facilitate replacement.

With these and other objects in view, attention is called to the drawings illustrating the preferred form of construction of 111% invention whereini igure 1 is an end elevation. a

ings, the invention consists of a suitable supporting frame 1, within the lower, frontal portion of which is journaled the horizontal,

receiving mold drum 2, while in the upper portionof the frame and backwardly of the drum' 2 'at an angle of about degrees, is ournaled a similar horizontal, pressure mold drum 3. These drums are cylindrical and the drum 2 is journaleddirectly in the frame 1' as shown at a and 5, while the drum 3 floats upon the drum'2,be1ng for this purpose journaled in the blocks 22, which are freely and slidably mounted between the guide rods 8 and 9. These blocks 22 travel in a path indicated by a straight line disposed at an angle of about 15 degrees toward the perpendicular from a line extended through the axes of the two drums.

The outer extendedends of the drums are provided with rigidly mounted equal and intermeshing gears 6 and 7, so that the rotation of the drum 2 will cause the equal rotation of the drum The guide rods 8 and 9 are disposed at an. angle inclined backwardly from the perpendicular, as shown, so as to expose a suflicient portion of the upper face of the drum 2 to receive and carry the material deposited thereupon, under the drum 3.

v The drum 3 thus 7 ounted over the drum 2, at anangle thereto rom the perpendicular of approximately 45 degrees, and floating resiliently thereupon in a path about 15 degrees nearer the perpendicular than is the line joining the axes of the two drums, permits lumps or accumulations of material to pass readily between the drums, which separate slightly for this purpose without shearing the briquets. In other words, the

result of this angular mounting of the drums, in connection with the deviating line of travel of the upper drum moving between its guides as it separates from the lower drum, and the interrelation of the slopesof the connecting gear teeth, is, on the drums moving apart to pass an acmlmulation of material, to cause-the upper pressure; drum to move upward and away from the lower receivin rum on a line nearer to the perendicu ar by about 15 degrees than is the me joining the axes of the drums, which is found by experience to maintain theniolds 20 in relative register oralinement so as to prevent the shearing or hreakingofthe briuets. q Immediately above the drum 3 and at each end thereof, is mounted a tensioning element,

otally suspended by the-upper arms 13 of the toggles 11 to the upper part of the frame 1,

while the lower arms 12 are pivoted within.

the mortises 23 formed in the upper part of the blocks 22. The bar passes slidingly through the plate 18 of the frame 1 and ex tends backwardly in the form of a screw threaded rod 14, having a washer 15 and nut 16, and carrying a compression spring 17 mounted between the washer 15 and the plate 18. Thus as material passes between the drums 2 and 8, and as the drum-3 is forced upwardly, the-tensioning device referred to offers the required degree of resistance against the drum 3 moving away from the drum 2.

Upon the outer curved surfaces of the drums 2 and 3 are mounted a plurality of separable and detachable halt" molds 20. These molds are individual and'similar for both drums, are formed shown in Fig. 5,

and are mounted by bolts 21 piercing the drums from the inside and screwing into the shanks 24. The molds cover the entire surfaces of the driims, with the half molds of one drum'registering with those of the other, so.that each pair of oppositely disposed half molds will register as the drums rotate, and thus cooperate to mold the briquets to the required form. As shown in the drawings, the molds are mounted in stepped or staggered or over-lapped relation, in order to include as many molds as possible upon the surfaces of the drums. Should one mold become broken,'it may be readily removed and the new one inserted by this method of construction.

Immediately above the drum 2 is mounted a compression, roller 25, same being 'hori-' zontally ournaled at either end in the adjustable pillow blocks 26 and'in alinement with the drum 2. The blocks 26 are slidingly mounted between the guides 27 and 28, while compression springs 29 mountedover rods 30 and extended between the blocks 26 and the upper spaced cross bars 31 Y tend to depress the blocks 26, and to hold.

' the compression roller 25. down upon the surface of the drum 2. Adjustment screws 32 extend through the bars 31 and springs 29 and engage the blocks 26, as means for adjusting the roller 25 relative to the drum 2. A s I rocket 57 is mounted on the extended Thus, as material end 0 the roller. 25. passes over the drum 2, the compression roller 25 operates tcevenly distribute and spread the material i) the re uired thickness uponthe drum 2 and into t e lower molds mountedupon the drum 2. Then as'the sheet of material passes on over the drum 2 and under the drum 3, the-molds on drum 3 registering upon the molds on drum 2, will complete the 'forming of the briquets 60.,

incense which are discharged by gravity down the A receiving hopper 35 is mounted updrum 2, equal in length to the drum, which port is provided with a number of sliding gates 37, each of which may be regulated up or down by means of the screws 38 so as to increase or decrease the size of the opening at any point, as desired, to regulate the amount of material 42 deposited upon the drum 2. A set of revolving scrapers 40 are mounted longitudinally withinthe hopper 35, upon the shaft 43, the latter being journaled at the ends in adjustable pillow blocks l1, and these scrapers operate to constantly keep the sides of the hopper 35 clean and free of material. The scrapers t0 and shaft 43 may be resiliently mounted for vertical movement by means of coil springs 63 mounted over pins 64, and thus adapted to press'downwardly upon the blocks 11 which move freely within the guides 68. The ends of the shaft 13 are extended and the gear .46 and sprocket 56 are mounted thereon. A door 15 is provided in the lower frontal portion of the hopper 35 for cleaning purposes.

" Power is supplied to the machine by means of the gear 50 mounted at the end of tated by means of the gear 46 meshing with the gear 6 of the drum 2. The compression roller 25 is rotated by means of a sprocket chain 55 extended between the sprocket wheel 56 at the end of the shaft 4:3 and the sprocket wheel 57 upon the outer end of the compression roller 25.
